Develop your algebraic equation solving skills through playing a Bingo game. The goal is to transfer the player’s skill level to solving complex algebra equations mentally. This game will take you step by step through the process of learning how to solve the most basic equation up through multiple-step equations by way of 13 different levels and it will allow you to choose from a variety of Bingo games from straight-line Bingo through multiple patterns of Bingo all the way up to Black-out Bingo if you choose. The game will keep track of your time and points to be able to compete with others as well as yourself.

It can also be used an Algebra tutorial for anyone preparing for a standardized test such as the S.A.T. or A.C.T.

It is an iOS app version of a game he played with his students for years with an overhead projector! Alge-Bingo won the 2012 National STEM Video Game Challenge in the Secondary Teacher Division sponsored by Sesame Street. It is being re-released in 2020 with updates for new screen sizes, more accurate and faster coding, along with new animations and sound effects. And for the first time, Alge-Bingo is FREE!
